Is ventilation important for pig breeding? Or is lighting important? Hear what the experts have to say

In order to prevent diseases in live pig farming, most farmers will give them sufficient light and ventilation, so which of the two is more important? This question shows that you are aware of the impact of the environment on pig farming. Today, Nanshang Technology Xiaobian Zhu Xiaoba Let me talk to you about the topic of pig house environment.

The benefits of different types of lighting

Long ago, studies have shown that light has a direct effect on pig survival, behavior and production.

1. Ultraviolet rays

Ultraviolet rays in the light have strong biological effects. Appropriate ultraviolet rays can convert 7-dehydrocholesterol in pig skin into VD3, which can promote the absorption of calcium in pig intestines, promote bone growth and development, and prevent rickets. Promote the metabolism of pigs, improve the productivity of pigs, and reduce the ratio of feed to meat; UV rays can also play a role in sterilization and increase immunity. However, it is not advisable to over-irradiate, as it will cause skin damage to pigs.

2. Infrared

Infrared has a photothermal effect, which can adjust the thermal function of pigs, promote blood circulation of pig skin, accelerate metabolism and cell regeneration, and have certain analgesic, anti-inflammatory and wound healing effects;

At the same time, bathing in a certain amount of sunlight can make pigs happy and reduce stress. Infrared rays also have the effect of sterilizing and promoting cell maturation, and can kill some negative parasites. However, prolonged exposure to sunlight can easily cause “sunburn.”

3. Night light

Increasing the light at night can improve the pig’s feed intake, increase nutrition and promote growth. It can also promote the maturity of pigs to a certain extent.

2. The effect of different types of light on different pigs

Some foreign studies have shown that light has different effects on different pigs.

1. Boars: Light within a certain range can promote the sexual maturity of young boars and improve the sperm quality and semen concentration of breeding boars.

2. Gilts: Prolonged light exposure can promote the sexual maturity of gilts.

3. Breeding and pregnant sows: Extending the light time before breeding and during pregnancy can promote the secretion of estradione and progesterone in sows, and enhance the function of ovary and uterus.

4. Lactating sows and piglets: Adding light to lactating sows can stimulate the secretion of prolactin. Increased milk production can increase piglet weaning weight.

5. Weaned piglets: Weaned piglets will not eat in the dark, and prolonged light can increase the feed intake of weaned piglets.

In view of the fact that they are all closed pig houses, the subject can use incandescent lamps and transparent glass windows to increase the lighting of the pig houses.

3. Pig house ventilation

关于通风，存在不少争议，不过有一些共识性的东西南商科技小编猪小八跟大家分享一下：

There is a lot of controversy about ventilation, but there are some consensuses to share with you:

1. Poor ventilation will increase stress: some pig houses have high breeding density, but they are not properly ventilated, the ammonia and sulfur in the air will increase, and the odor will increase. On the one hand, it will increase the stress of the pig herd; great influence. After such pigs were slaughtered, obvious signs of contamination in the lungs could be seen. After African swine fever, many pig farms have adopted fan water curtains to provide ventilation and increase the comfort of pigs.

2. Airborne germs

After the outbreak of African swine fever, the prevention and control of many pig farms was very detailed, but it was also lost. The problem lies in the air. There is a lot of invisible dust in the air. These dusts may carry a large amount of germs and viruses, so cause disease in pigs.

Some breeding farms with good conditions are equipped with air filtration devices to purify the air. Environmental control and animal welfare can improve production efficiency to a certain extent. You can lean towards this aspect when you have enough energy and funds.

The ventilation and lighting of the pig house, professionally, belong to the environmental control of the five elements of pig raising, and to put it bluntly, it belongs to animal welfare. Ventilation and light are not a matter of choosing one or the other, but both can improve production efficiency and can be used at the same time.
